DIY Morse Code Trainer

By Anthony Guiller E. Urbano, DU1AU
January 2020

I have built an improvised trainer that uses a guitar tuner’s tone generator feature to generate the tone needed to operate a Morse code key. The tone generator (guitar tuner) and the power supply (two AA batteries) are tightly placed in a small pocket-sized enclosure with a straight key mounted at the top, making the Morse code trainer a bring-anywhere ultra portable tool for code practice.
